Last night we migrated Jenkins (http://ci.eionet.europa.eu/) to a new server on CloudVPS. It has also been installed as a Docker container. We did not migrate the history, so the build numbers are starting from one again. After a couple of check-ins, you'll have the five generation history you're used to. When I checked, none of the Java projects were able to build. Expect some build failures while they solve it.
The old server will be available at ci-old.eionet.europa.eu for a couple of weeks.
